Popular note taking and annotation app Notability is getting an update today for both iPad and Mac that includes improved Apple Pencil support, new themes, copy & paste for pages, and more.

For the iOS app, version 6.2.0 brings enhanced Apple Pencil integration that adds supports for improved palm rejection and one finger scrolling. “With these improvements, Notability offers the most fluid writing experience on iPad Pro, so customers can focus more easily on their ideas and notes. In addition, the update supports copy and pasting pages between notes, saving time.”

In addition, the updated iOS app is receiving some refreshed themes today for the spring season that users can find tucked under settings, and a new “define” button for non-English languages.

And Mac users are also getting the ability to copy and paste pages between notes with today’s update to version 2.2.0 of the Mac app. Other new features in the update include an “improved text box insertion on PDFs” and the same Define button for non-English languages that the updated iOS app received.

FiftyThree, the developers behind the popular drawing app Paper, today announced it’s releasing an SDK that will let all developers take advantage of its Pencil stylus for iOS devices. First launched last year alongside an update to Paper, Pencil is a $60 Bluetooth stylus for the drawing app that aims to offer a realistic pencil-to-paper drawing experience.

The SDK will allow for a smooth experience with the Pencil stylus in other apps and that also means in some cases FiftyThree will be working to improve the apps of its direct competitors while hopefully selling its stylus as a platform in the process. Devs will get access to palm rejection, erase, easy pairing, and all the pencil and touch classifiers the company uses in the Paper app. Support for surface pressure is also arriving with iOS 8: expand full story

The app now supports new palm rejection, erase, and blend features for Pencil:

Palm Rejection— Pencil and Paper work together to produce the most sophisticated and effective palm rejection in any app available today. No setup, no calibration, just natural feeling writing and drawing.

Erase— Pencil’s unique built-in eraser lets you get down to what’s essential.

Blend— Pencil takes care of the lines so you can use your fingers to blend colors on the page and smooth rough edges without ever picking up a tool.

FiftyThree has been taking preorders of Pencil as an in-app purchase directly in the Paper iPad app as well as through its website. It’s selling a graphite model for $50 and a walnut model for $60. While the first preorders will begin shipping this week, an update on its Twitter account today notes new orders will take around in 3-4 weeks.
